Remove line 58 info.close() and try again.
That should probably work.

Make sure that your 'coursesLine' when split into 'courses' has only 3 values because your 'coursesNUM' is 3.
Something like this-
String coursesLine = "Java C++ Python";
String[] courses = coursesLine.split(" ");
for(String c:courses)
System.out.println(c);
OR remove the variable 'coursesNUM' and inside the for loop you can use courses.length to iterate.

String coursesLine = info.nextLine();
String[] courses = coursesLine.split(" ");
System.out.print("The courses for this semester are:");
for (int i = 0; i < courses.length; i++) {
System.out.print(" " + courses[i]);
}
This can remove array index out of bounds exception.
